Tasks this bears on
Frozen sections during surgery
Reading a rapidly frozen sample while the surgeon waits, and calling the result into the theatre.
Still human-led✓ Evidence-backed
Where this applies
United States, a retrospective study of procurement biopsies from 2,431 deceased-donor kidneys. It says frozen sections present challenges for histological scoring, leading to inter- and intra-observer variability and inappropriate discard; its model's whole-slide features correlated with pathologists' scores and were more strongly associated with graft outcomes, and it suggests 110 of 398 kidneys discarded for biopsy findings could have had similar survival. Organ allocation, not intraoperative tumour frozen sections.
What this means
Frozen sections are hard for pathologists too, and that is where a model could add a check — so far only in retrospect.
What it does not yet show
Retrospective, about donor kidneys; it says nothing about frozen sections during cancer surgery.
What you can check
Open the Kidney International study on deep learning for frozen procurement kidney biopsies and find "inappropriate discard".
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 1 linked judgement above stand where they were.
